In a reformation unit, which equipment uses low-voltage electricity and which uses high-voltage electricity?
Large motors. Our workshop has a 220kw motor that operates on 380V electricity; it is said to be the largest low-voltage motor in our factory.
High-voltage electricity is used for high-power motors, while low voltage is used for small motors. For example, high voltage is applied to hydrogen compression, reforming cycle hydrogen, and large feed pump products, whereas low voltage is used for other applications.
The high-pressure electrical equipment used in the reforming unit includes a pre-hydrogenation feed pump, a bottom pump for the reforming product separation tank, a bottom pump for the xylene column, a medium-pressure boiler feed water pump, a pre-hydrogenation circulation compressor, a xylene hydrogenation circulation compressor, and an ammonia compressor. Others use low-voltage electricity
As a supplementary note, in some reforming units, the compressors in the reforming cycle machines and the reforming boosters use high-voltage electricity, while others use steam turbines.
